Adrestia

The Adrestia was a trireme captained by the Greek captain Barnabas in the service of the Spartan mercenary Kassandra during the Peloponnesian War. The ship was once in the service of the Cyclops of Kephallonia, but Kassandra helped Barnabas take control of the ship following the Cyclops' death in 431 BC, and Kassandra recruited lieutenants from associates made during her quests to reunite her family, defeat the Cult of Kosmas, and fight in the war.
